Excessive Heat Warning Extended Through Friday For La Mesa

LA MESA, CA — An excessive heat warning has been extended for the San Diego region as a record-breaking heat wave continues to bring scorching temperatures to California.

Temperatures have soared above 100 degrees every day since last Wednesday in Southern California, with little relief in sight until this weekend.

An excessive heat warning that has been in effect all weekend was extended until 8 p.m. Friday for San Diego County, including the city of La Mesa, according to the National Weather Service. Dangerously hot conditions were expected in the region.

"Extreme heat will significantly increase the potential for heat-related illnesses, particularly for those working or participating in outdoor activities," the NWS warned.

The weather service advised community members to stay indoors and seek air-conditioned buildings. People should also drink plenty of water and avoid dehydrating alcoholic, sugary or caffeinated drinks; dress in lightweight, light-colored clothing; eat small but more frequent meals; and keep an eye on those who may be particularly vulnerable to the heat, including small children and the elderly.

"Know the signs and symptoms of heat exhaustion and heat stroke," the NWS advised.
